    Abstract

    Talc filled polypropylene (PP) composites filled with different loadings of talc were die-drawn at 15°C below the melting temperature using different draw rates. The objective was to study the effect of draw rate on polymer orientation and flexural modulus achieved in the presence of particles, along with void growth and deformation. A lower extent of crystalline orientation was achieved in the drawn PP-talc composite with 7.8 vol% of talc than in the drawn composite with 3.5 vol% of talc and in the drawn neat PP. The crystalline c-axis orientation was independent of draw rate over the range studied while the void volume fraction, the mean void aspect ratio and the flexural modulus leveled off only at higher draw rates. The effect of voiding in drawn composites appeared to be offset by the increased orientation in amorphous polymer regions.
